* include/bits/char_traits.h: Remove generic definitions.
* include/bits/streambuf_iterator.h (istreambuf_iterator): Use
eof, not -2.
* include/bits/istream.tcc (istream::readsome): Don't check
against eof, instead use constants.
(istream::sync): Same.
(istream::sentry::sentry): Use eq_int_type.
(istream::get): Same.
* include/bits/ostream.tcc: Change __pad to
__pad<_CharT, _Traits>::_S_pad.
* include/bits/locale_facets.h: Add __pad_traits generic and
ostreambuf_iterator specialization.
* include/bits/locale_facets.tcc: Change __pad into struct __pad
with a _CharT and _Traits template parameter and _S_pad static
member function.
* src/locale-inst.cc: Update __pad instantiations.
* include/std/std_fstream.h: Declare _M_underflow_common
specializations.
* src/fstream.cc: New. Add _M_underflow_common specializations.
* include/bits/fstream.tcc (filebuf::close): Use traits_type.
(filebuf::_M_underflow_common(bool)): Remove generic version, as
sys_ungetc and custom int_types don't get along.
* include/std/std_streambuf.h: Add _M_pos.
* src/Makefile.am (sources): Add fstream.cc.
* src/Makefile.in: Regenerate.
* testsuite/21_strings/capacity.cc: Add char_traits specializations.
* testsuite/22_locale/codecvt_members_unicode_char.cc: Same.
* testsuite/22_locale/codecvt_members_unicode_wchar_t.cc: Same.
* testsuite/22_locale/ctor_copy_dtor.cc: Same.
* testsuite/27_io/filebuf_virtuals.cc (test07): Move to...
* testsuite/27_io/filebuf.cc: ...here.
* testsuite/testsuite_hooks.h: Add gnu_char, gnu_int, char_traits
specialization for both.
* testsuite/27_io/streambuf.cc: Add instantiation test,
testsuite_hooks include.
* testsuite/27_io/istream.cc: Same.
* testsuite/27_io/ostream.cc: Same.
* testsuite/27_io/fstream.cc: Same.
* testsuite/27_io/stringstream.cc: Same.
